徴とする切替器駆動回路。a switching device equipped with a drive coil; a positive power supply that generates a positive voltage; a negative power supply that generates a negative voltage; and selectively switching and applying either the positive power supply voltage or the negative power supply voltage to the drive coil. A switching device drive circuit comprising: a parallel circuit of a resistor and a capacitor connected in series with the drive coil; the resistor limits the current flowing out from the power supply during steady state; , when the switch is switched, the starting current of the drive coil is increased by releasing the charge stored in the capacitor, and then the charge is stored in the capacitor depending on the voltage polarity after the switch. Features a switching device drive circuit.
